Concept: The question tests on the basics of Profit/Loss(Percentage)

Solution:

The profit % will be the same irrespective of whether it is 1 apple or 100 apples as long as we take an equal number when calculating CP and SP.

let CP of 1 apple = 100

then SP of 1 apple = 125

Profit% = SP−CPCP100=125−100100100SP−CPCP100=125−100100100 = 25%
